Medical - Medical (general) | | Latvian term or phrase: doplerogrāfiskā stara novājināšanās simptoms | Hi Latvian linguists,
Can you tell me what this sentence might mean? It's a medical report, this is the only part this remains unclear.
Kind regards,
James |

| | attenuated wave symptom in Doppler sonography | Explanation:
attenuated wave symptom in Doppler sonography
Since the Doppler sonography employs a sound wave, but not a beam as some other diagnostic imaging devices, all I can think of is the above mentioned.
Sonography can be enhanced with Doppler measurements, which employ the Doppler effect to assess whether structures (usually blood) are moving towards or away from the probe, and its relative velocity.
When sound travels through a medium, its intensity diminishes with distance. In idealized materials, sound pressure (signal amplitude) is only reduced by the spreading of the wave. Natural materials, however, all produce an effect which further weakens the sound. This further weakening results from scattering and absorption. Scattering is the reflection of the sound in directions other than its original direction of propagation. Absorption is the conversion of the sound energy to other forms of energy. The combined effect of scattering and absorption is called attenuation. Ultrasonic attenuation is the decay rate of the wave as it propagates through material.
